The application of gene GmSUT6.
Background technology
Higher plant is the autotroph being made of autotrophic organ and heterotrophism organ.Heterotrophism organ needs the light of autotrophic organ
Product is closed to maintain growth and development.The photoassimilates 80% synthesized in plant maturation blade etc. " source " organ all pass through plant
Skeleton transports root, flower, fruit etc. " library " organ.Sucrose is one of green plants photoassimilates, and most
Photosynthate trasport and the principal mode of distribution in higher plant body (Yang Shuan etc., 2005;Bai Xuemei etc., 2006).Sucrose is being planted
The mode of orientation transport and distribution not only regulates and controls the entire growth and development process of plant in strain, also determines the yield and product of crop
Matter.And durings " source " organ of sucrose loading, the long-distance transportation of bast and the unloading of " library " organ etc., sucrose transports egg
In vain (Sucrose Transporter or Sucrose Carrier, SUT or SUC) play an important role (Williams et
al.,2000;Wu Xiaodan etc., 2006;Ruan Yanye etc., 2007).Sucrose transporter belongs to easyization diffusion superfamily (Major
Facilitator Superfamily, MFS), there is typical 12 transmembrane domains (Stolz et al., 1999).Sucrose
Transport protein not only plays a crucial role in the loading of bast and unloading, but also is distributed in plant and homobium or pathogen carbon
In it is same it is most important (Wahl et al., 2010;Wippel et al.,2010).
